Register 20: DMA Bus Error Clear (DMAERRCLR), offset 0x04C
The DMAERRCLR register is used to read and clear the DMA bus error status. The error status
will be set if the μDMA controller encountered a bus error while performing a DMA transfer. If a bus
error occurs on a channel, that channel will be automatically disabled by the μDMA controller. The
other channels are unaffected.
